OXIDIZING APPARATUS.

Application filed March 15, 1917.

To all whom it may concern:

Be it known that I, MANLEY J. CHAPLIN, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Oxidizing Apparatus, of which the following is a specification.

This invention relates to oxidizing apparatus and, more specifically, to improvements in retorts of the class illustrated and described in United States patent No. 1,183,838, issued May 16, 1916.

The object of the present invention is the perfecting of retorts of this character so as to render the same more eflicient and capable of being operated uninterruptedly.

To these ends, the invention consists in the novel construction, adaptation and combination of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical transverse section of an oxidizing furnace embodying my improvements. Fig. 2 is a horizontal section through 22 of Fig. 1. Fig. 3 is a view partly in side elevation and partly in vertical section to illustrate the appliances for progressively removing deposits from the wall and floor of the retorting chamber. Fig. 4 is a detail sectional view through 4-4 of Fig. 3.

In said drawings, the reference numeral 5 represents a conoidal shaped wall extending from a floor 6 to an extension 7 which serves as a chimney for the gaseous products of combustion formed in the chamber 8 inclosed by said wall and in the subjacent communicating chamber 9.

10 represents an oil or gas burner provided in the chamber 9 and is preferably disposed below a baflle plate 11 whose ofhce is to direct the flames and hot gases against the inner surface of the wall 5.

12 represents adamper plate suspended by a rod 13 from a crank-shaft 1 L extending through the chimney and is actuated as by means of a crank handle 14 to regulate the draft by closing, more or less, the effective opening between the combustion chamber and the chimney.

15 represents a casing wall which incloses the aforesaid chamber 9 and also a space 16 surrounding the conoidal Wall 5 Specification of Letters Patent.

Serial No. 154,987.

to afford with the latter what will be hereinafter designated the retorting chamber.

Rigidly secured to the casing wall 15 is a roof plate 17 which extends for a distance inwardly and thence downwardly as a tubular apron 18. For feeding material upon the outer peripheral surface 5 of the wall and adjacent to the top thereof, I provide an annular shaped receptacle 19 which is rotatably supported by rollers 20 interposed between a shoulder 21 of the receptacle and a circular track 22 provided on the chimney 7 Said receptacle is provided with a circumferential flange 23 overlying the casing roof plate 17 and provided with gear teeth 23 engaged by a toothed pinion 24 upon a shaft 24 which may be driven as by a belt, not shown, passing about a pulley 24: mounted on said shaft, whereby the receptaole may be rotated. Within said receptacle is an annular partition 25 which, with the walls 19 furnish a circular trough 26.

Portions of said partitions are foraminated, as at 27 (Fig. 2), to afford communication with conduits 28 which terminate in spouts 28 extending into the space between the wall 5 and the apronlS. Each of these spouts is formed with an outer wall which is inclined, as at 28 to cause material to be delivered upon the wall surface 5 close to the upper end thereof.

29 represents conveyer for supplying the material to be treated into the trough 26 to be fed, as required, through the various spouts. To regulate such feed, I provide within the trough a number of blades 30 having upright stems 30 journaled in bracket attachments 31 of the chimney 7. Each of said stems is provided with a crank arm 30 -and are operatively connected with each other and to an operating lever 32, Fig. 2, by means of links 33.

By adjusting the blades to be radial, or nearly so, to the centerof the revolution, the material will be prevented from traveling with the receptacle, with a maximum delivery through the foraminations 27 but by turning the blades through the instrumen-- tality of the lever 32, the feeding of the material will diminish to a minimum when the blades are brought into rectangular positions with respect to planes extending radially of the receptacle.

Referring to Fig. 3, 34: represent chains depending from the receptacle 19 and located between the respective spouts 28 for the purpose of scraping any deposits from the wall surface 5 Such scraper chains advantageously may be connected by stay chains 35, as shown, for the purpose of obviating lateral deflection due to friction while in their orbital travel with the re ceptacle.

36 represents an opening provided in the roof 17 outside of apron 18 for the delivery of the fumes or gaseous products from material treated in the retort.

In the casing wall 15 is provided an open ing 37 into which slag is discharged from the retort floor by means of a scraper 38 disposed substantially as shown in Fig. 4, and which is revolubly carried by means of a rod 39 with the receptacle 19.

At diametrically opposite sides, desirably, of the retort from said scraper, I provide a toothed implement 40 connected by rod 4:1 with said receptacle for the purpose of breaking up any deposit upon the floor to facilitate thework of removing the slag by means of the scraper. Said discharge opening is connected by a duct 4'2 with a case L3 in which is fitted a rotatable wheel 44 and provided with peripherally disposed pocket-s45 into which is successively delivered the slag from the retort.

By supplying the slag to one side of the wheel as indicated in Fig. 1, the unbalanced weight of the slag will cause the wheel to rotate and deposit the same into a delivery pipe 46. By means of such devices, the wheel e'l not only serves to transpose the slag but. also acts to prevent the flow of air into the retort.

In operation, the material is delivered into the trough 26 of receptacle 19 and upon Y the partition 25 which rotates with the receptacle. By adjusting the blades 30 is regulated the quantity of the material which is fed through the holes of said partition into the spouts 28 and delivered against the upper portion of the surface 5 of wall 5.

This wall is maintained sufficiently hot by means of the burner 10'.

The material thus distributed upon the hot wall 5 by means of the revolving spouts is affected to have the volatile portion of the material driven off in the form of gas which flows under the bottom of the apron 18 and thence through the opening 36 to the apparatus (not shown) in which the gases are oxidized or otherwise treated.

The residue or slag is prevented by the action of chains 34: from adhering to the 'furnace wall 5 and falls to the floor 6 from which it is prevented from adhering or, at least, is dislodged therefrom by the toothed 1. An annular retort of the class described, having a conoidal inner wall affording a furnace within the same, a chimney extending from the latter, a rotary receptacle surrounding said chimney and having spouts extending into the retort, a foraminated -partition provided in' said receptacle, means to revolve said receptacle, and adjustable means extending into the rec'ep tacle and rendered operable by the rotation of the latter to effect the feeding of said material through the partition into the respective spouts.

2-. In combination with a retort of the class described, an annular receptacle rotatable about the axis of said furnace and having delivery spouts extending intothe furnace, said receptacle being provided in.- termediate its height with a foraminated partition, a plurality of blades extending into said receptacle, means torotate the receptacle, and means to coincidently adjust all of the blades to regulate the discharge of material through the various spouts during the rotation of the receptacle.

8. In a retort having a centrally disposed furnace provided with a conoidal wall,v

power-rotated devices having spouts extending into the retort for depositing ma terial upon: the outer surface of said wall, and means carried by said devices for scraping the slag from said wall surface.

4. In a retort having an outer circular wall, a furnace having a conoidal wall disposed centrally of the aforesaid wall, a roof wall provided with a gas delivery opening in proximity to the first-named wall, means shape, a stationary floor connecting the lower end of said furnace wall wlth said peripheral wall, means to feed material to be treated upon the furnace wall, and revoluble means to removethe slag from said.

furnace wall and the floor and direct the slag into said discharge opening- Signed at Seattle, Washington, day of March, 1917 V MANLEY J. CHAPLIN.
